Required knowledge and skills to develop iOS applications

In design, Gestalt principles often show up in logos. So, the logo of the World Wildlife Fund is a panda, which consists of closely spaced black spots on a white background.

And the principle of proximity can be seen in the application registration form: signatures located close to the text fields suggest what exactly needs to be entered in a particular field.

Application UI design

UI (user interface) is the stage of user interface development, at which all interface elements are created: buttons, menus, visual design. It is important that UI and UX go hand in hand, then it will be easier for the user to interact with the application.

There are also several principles for designing an interface.

The user should be able to easily navigate the interface. To do this, you should use concise elements, and place components in easily accessible places.

Icons and illustrations in the application should be clear and not overloaded with images, and the text should be easy to read and legible.

Use guidelines (manufacturers’ instructions and requirements). They describe both UX and UI principles for different platforms – for Android there is the Google Material Design System, and for iOS – the Apple Human Interface Guideline.

Be sure to test your app on different screen sizes. Optimizing the design for different devices will help you avoid disappearing buttons, truncation of elements that extend beyond the edges of the screen, too small fonts, and other ill-conceived scaling problems.

To create the perfect design, it is important to remember that you are creating an application for people – and they should get the most out of it.

How to understand if the design is user-friendly?

The finished application must be tested, and usability testing is one of the most important stages of this process. When testing, we evaluate the application according to several parameters:

efficiency – whether the user achieves his goals;

effectiveness – the time that he spends on achieving them;

satisfaction with user experience and quality of service.

Before the release of the application, the design can be tested in an interactive or clickable prototype (for example, in the Figma service). There are also other services that demonstrate the process of interacting with the application – Userlytics, UserTesting, etc.

Ideally, testing occurs throughout the development of an application. Constant health checks and interface evaluation on screens with different resolutions will allow you to find and eradicate errors even before the release.

Do not forget about testing after the application gets into the app stores (stores), and after the release of new versions. It is not uncommon that even after a small update or the addition of new features, something “rides” on existing pages.

iOS Application Development: Basics, Programs, Examples

Development of iOS applications is a promising direction in the field of IT. If you’ve been programming for a while, you’ve probably thought about trying your hand at creating a mobile application for the iPhone, but something might have been stopping you. But you could have mastered this niche a long time ago and started earning good money.

In order not to waste time, start right now, and our detailed instructions will help you. Below you will find information: from the basics to small nuances, armed with which you will know what knowledge and skills are required to create mobile applications for iOS, as well as what stages this process consists of. If you have an idea for your product, then this is already a big step, and everything else is a matter of technique!

Required knowledge and skills to develop iOS applications

Creating any applications, including for iOS devices, requires quite extensive knowledge. The programmer also needs to know mathematics and logic, even if it is not needed at the initial stage. The development of modern technologies has given developers the opportunity not to study the PC architecture thoroughly, however, understanding the basics (number systems and how to convert them, the speed of subroutines, the effectiveness of various algorithms) in this area is necessary.

A programmer specializing in iOS applications needs to understand at a professional level the operating systems from Apple (both macOS and iOS). Let’s add a mandatory requirement for an iOS developer, which consists in knowledge of programming languages ​​created for this architecture (Objective-C, Swift). Delphi, C++, C# or VB.NET skills are not particularly needed here.

Of course, it won’t hurt to know at least the basics of the same C++, especially since its elements are also found in “apple” languages. And yet, Objective-C is the most popular in development for Apple devices. This language appeared in the early 1980s (that is, much earlier than C ++). A younger Swift was released by the creators in 2014. Both Objective-C and Swift are heavily used in development. The first is needed to support old software, while the second is used to write all new applications. For this reason, it is desirable to know both languages.

Required knowledge and skills to develop iOS applications

Experienced developers will find it much easier to master iOS app programming. But you can start developing in this direction even without any skills in developing computer programs. To create applications for iOS, there is the PaintCode environment, which appeared due to the active development of NoCode technologies.

But you need to know English, since all the relevant development documentation on the Apple website is written in it. In general, English plays a key role in programming.
